To all who-mI it may conce-m.'

Be it known that l, JACOB KRABILL, a citizen of the United States, residing at Mansiield, in the county i Ohio, have invented new and useful lmproveinents in Ore-Separators, oi'l which the following is a speeiiication.

Thi 'f` vention relates to an improved mapted to operate upon dry pulveral, such as pulver-ized ore, to sepalighter from the heavier' constituents and the object of the invention is to a device of this character which is ln construction` comparatively cheap 4 ifacture, and the parts of which are se a1...niged as to be readily adjustable to .regula-ie the feed as well as to cont-rol the f elements in their action upon the a separated,

`Wi these and other objects in view the inven` .n resides in the .novel construction of elements and their .arrangement in operative combina in., hereinafter fully described and claimed In the accompanying drawings, Figure 1 is a side elevation of an apparatus constructed in accordance with the present invention. Fig. 2 is a transverse sectional view upon the line 2`2 of Fig. 1. Fig. 3 is a lf'ingitudinal sectional view of the rotary "bum, illustrating its connection with thc stationary drum.

the accompal'iving drawings the nuirral l designates the lrame olf the device.

a This frame 1 has one of its ends provided with a settling box 2 havingl a pipe connection 3 with a suction i'an 4. lhis pipe 3 is provided with a suitable sliding valve 5 having a longitudinally extending stem 6 mounted in suitable bearings and provided with an operating handle 7 positioned adjacent the opposite end ofthe frame. The deflector box 2 is provided with a spout S connected 'th an inclined stationary separatingI cylder 9. This cylinder .fl is provided at its e end with a collar l() having' a strap 11 by which it is supported from the longitudinal mbers of the trame 1. 'lhc collar 1() and drum 9 are each provided with a suitable aiming opening adapted for the reception of ore to of Richland and State of a spout 12 connected with a feed hopper 13. The spout l2 is provided with a rotary drum 14 and is also provided with an inclined plate 15, whereby the material within the hopper 13 is fed directly upon the upper portion of the drum 14. The spout l2 is also l provided with a hinged valve 16 having its and this flange 1S) is lower edge. contacting the periphery of the drum 14. The valve 16 is provided with suitable valve stem 1.7 mounted in suitable bearings and having its operating` handle 18 positioned adjacent the. handle 7 of the valve 5. By this construction it will be noted that the material from the hopper 13 directed upon the drinn 14 b v the inclined plate 15 may be regulated in its flow through the spout to the separating cylinders by the valve 16. The drum 14 is provided .with a suitable shaft extending upon the side' of tho spout l2 and provided with a adapted for engagement with an endless belt 17, and this belt 17 is adapted to engage a similar pulley 18 connected with -a suitable motor or other operating device.

The collar is provided with a flange 19,

provided with a plurality ol' rollers 2(-). The numeral 21 designates the rotary drum or cylinder ot' the device. 'This drum 21 is adapted to be positioned within 'the collar 10 adjacent the end ot the cylinder i), and is contacted by the. rollers 2() .vherelryv friction caused b v the rotation of the drum is minimized. 'lhe drum 2l has it :.ol'iposite end closed and is provided with a plurality of cut away portions or openings extending in spaced relation with each other around the annular circumference of the drum. These openings 22 are positioned directlyY above a spoilt 23 connected with a suitable receiving .vessel 24.

An agitator shaft 25 extends axially through the cylinders 9 and 2l, passing through the caps at both ends thereof.. The shaft 25 is provided with agitator brushes 26, and these brushes are positioned a suitable distance away from the interior surfaces of the cylinders l) and Il 'whereby the brushes being held t'ree troni'ontact, all rubbing or grinding of the ore against the drums'is obviated. The upper end olE the shaft 25 is consuitable pulley.

ne'cted With the motive power which rotates thel pulley i8 andV the roller lli, While the lower endd ol' the shaft 25 is extended through the closure of the cylinder 2l and through a suitable bracl-ret 27 provided upon one ol the vertical members of the trame. This end of the shaft is provided` with a conical recess adapted for engagement with a bearing` stud 28. This stud 25 provided with threads p'1d is adapted to work a threaded aperture provided upon a bracket 27. The end of the shaft 25 Within the bracket 27 is pro- Y vided with a suitable friction Wheel 2S, which contacts with a larger friction wheel 29,'also mounted in bearings within the bracket 27.

. The shaft ot the wheel 29 extending beyond the bracket 27 is provided with a smaller wheel 30 adapted to Contact with anannular surface 31 provided by the closure for the rotary cylinder 2i. By this construction it Will be notedthat as the agitator brushes 2,5 are rotated the shaft 25 imparts motionto Ythe rotary cylinder 21through the medium of the friction Wheels 28 29 and 30 contacting`with the annular surface 31 of the. closure of the cylinder, and th-at by this arrangement the ore :deposited within the cylinders is thoroughly agitated. l

ln the settling box 2 between the pipes 3 and 8 is a dcllector plate 32. This plate 32 is hingedly secured between 'the sides of the box 2 and is providedI with a regulating lhan- Clle 33l` by which the plate may be swung toward the pipe S of the cylinder or toward the pipe S of the suction fan ll to regulate the iloW bf air through the cylinders to the settling box'. By this arrangement it will be seen that the box 2 is provided with a partition which separates that part ol the box into which the air ilows from that part of the box from which it flows. The air carrying' the lighter particles must therefore dive beneath this partition in. passing fronrthe inlet to the outlet of the box. As a matter ol fact the practical result of'thc construction is that all. of the pulverized particles will collect upon the. inclined bottom 34 of the box 2. The box provided with a pi'voted door 35, and .when a sullicient quantity ot the material is collected upon the bottom 34, the door 35 will automatically open and allow the particles to slide out of the box. lt will be noted that the ilow of air through the `box 2 is readily regulated by the valve 5 connected with the outlet pipe 3.

Although the particles fed to the cylinders may be of the. same size, the heavier particles may be fri-able and so become-broken up as they are tossed around Within the cylinders.

ch broken particles becoming smaller bealso lighter and are carried away by the 'rent 4into the settlingbox. lt is of niderstood that the heaviest particles fall, in the rotary drum 21 and the flow of material from the feed box to through the openings 22 into the receptacle 24, the lighter particles oeing carried through the. cylinder 9 through the pipe. 8 to the settling box 2 by the air from the suction fan 4 previously desi ribs-d. By constructing the separator with the rotary drum 21, i@ will be noted that the brushes 26 may e positioned a suitable distance away from the cylinders, and that by this construction the grinding' or rubbing of the ore against the drums is entirely obviated, thus prolonging the life of the brushes and the cylinders.

Having' thus fully described the invention what is claimed new is:

l. The combinal ion with a stationary and a rotary cylinder, the rotary cylinder having a closed end and provided with a plurality of openings adjacent said end, a feed box positioned above one otthe cylinders, the stationary cylinder having an outlet communieating with a settling box, a suction fan connected with the settlingn box, a shaft extending axially' through the cylinders, rush members connected with said shaft and positioned a distance away from the cylinders, and means for rotating the shaft.
